Menu-guided test procedures for carrying out pressure tests on district heating pipes according to AGFW FW 602 (Germany): – Differential pressure measurement method (air) – Pressure measurement method (air) – Simultaneous pressure measurement (air) – Water pressure test

Menu item for recording measurement data from any EDS2 sensors. Different sensor types can be connected (pressure, temperature, flow) and their measured value is recorded simultaneously (max. 5 sensors). The storage interval is freely adjustable within a maximum measurement duration (depending on the number of sensors).

Integrated pump with a flow rate of approx. 20 l/h. The pump forwards gas via different available probes to the sensors. A nipple incl. filter on the upper side of the housing is used to connect probes to the instrument. Operating time is reduced by approx. 40% compared to diffusion version. Instrument dimensions with integrated pump: 171 x 78 x 43 mm Weight: approx. 380 g
